WILLARD E. swrrn'or woncnsm, 'MASSACHUSETTS,ASSIGNOR To UNITED STATES ENVELOPE COMPANY, or *srnm qrmnp, MASSACHUSETTS, A CORPORATION or MAINE.

To all whom it may concern I U.,fliwBefitilrnown that I, WILLARD SWIFT,

' vented a new and useful Improvement in a citizen of arcuaaea States, residing at Vorcester, in the county of Worcester and Commonwealth of Massachusetts,have inmade by folding a sheet of material, such as waterproof paper, and particularly to that type of cup which is provided on one of its si desswith a projecting flap or fin formed by anextension of one of the side flaps of the clip, to afford. a convenient means for holding the cup so that it maybe opened by the force of the water as from. a faucet,

as well as while drinking therefrom.

The objects of my invention are to provide a flap or filiWhiCh is normally inproper position when the cup is held in a dispensing cabinet to be conveniently Seized by the thumb and fingers, and also to reinforce the bottom of the cup in' order to increase its strength and prevent leakage. The above objects I accomplish by means ofth'e conv struction and arrangement of parts as shown in the accompanying drawings, and hereinafter described and pointed out in the annexed claim.

' Referring to'the drawings,

Figure 1 represents the blank from which my'improved drinking cup ismader.

Fig. 2 is a perspective view showing the method of folding one side flap'of the blankv over the other. 1

Fig. 3 is a side view showing the Side flaps folded and their edges fastened together.

Fig. 4 is a side view, as shown in Fig.3,

but showing the gummed surfaces at the lower edges of the body portion and side flaps.

Fig. 5 is a side view, as shown in Fig. 4, but with the lower gummed edges of the body portion and side flaps folded over and attached to the outer surfacesof the side flaps.

Fig. 6 is a side view as shown in Flg. 5, but with the projecting flap or fin folded back against the side flap of which it forms PAPER DRINKING-GU13.

showing the projecting flaporfin'in its normal position at right angles to the drinking cup. v

Figs. 8, 9, 10 and 11 illustrate a modified construction of the drinking cup.

Similar reference characters refer to Similar parts in the difierentv figures. "Tin ig. 'l. of the drawings, 1 represents the bodyportion efthe-blank ,innnn' i ql my improved drinking cup is folded, and 2, 3, are the side flaps. The bodyportion 1 is extended below the side flaps 2 and- 8 as .at l. and is preferably rounded at its lower corncrs 5. The side flaps 2 and 3' are adapted to be folded over the body '1 on tl1e'--broken' lines 6 and 7, respectively. The side llap'Q is substantially half the width of the body 1 and is provided on its outer side flap 3 is somewhat wider than the Side flap 2 so as to allow the edges of the.side flaps when folded to overlap and be fastened together near the center of the body 1, as hereinafter described. On the under side of the side flap 3 gum is applied to a surface 9 exteinling' its entire length and As shown in Fig. 9, the side flap 3 is first folded on the line 7 over the body 1, bringing the gumined surface 9 uppermost and the side flap 2 folded on the line 6 over the body 1, and its edge securely fastened to-the gummed surface 9 of the side flap 3, leaving the flap or fin 8 lying in contact with the side flap 3,-as shown in Fig. 3., 1

4 side with a lateral projection or fin 8. The

As shownin Fig. 1, gum is next applied to the extension 4 of/ the body portion 1,

and also to the outeli lower edges 11 and' and upon the side flaps and securely fastened thereto, as shown in Fig. 5.

In the process of folding, the gummed surfaces 11 and 12 are folded upon and se-;, curelv attached to the outer surface of the',;

side flaps 2 and 3. The gummed-extension 4 of the body portion 1 extends above the edges. of the side flaps and is attached directly to the outer Surfaces of the side'flaps. The drinking cup, therefore, has four thicknesses of materialit the line 13 of fold. The line 13 of-fo (1 occurs at some distance above the lower ends of the side lines of folds 6 and 7 and the extension 4.- of the body portion extends over the folded the cup is resisted by the strength of the.

material, there being no gummed joint at the corners.

The process of folding herein described folds the flap or fin S flat against/them flap 3. requiring it to be. raised'l)y hand into a position substantially at right angles to the drinking cup, in order that it may serve as a handle in filling the cup with water and in drinking from the cup. 'As the material from which the cup is made is stifl' and unyielding, this operation requires that the cup 7 should be firmly held while the free edge of the fin 8 is separated and the nt bodily g 2 i 1 o a raised position. The elasticity of the material, however, is sufiicient to restore the fin to its fiat position as soon as released.

In certain dispensing cabinets now in use, the cups are presented broadside to the user and require to be forcibly pulled from the cabinet by seizing the fin 8. Under these conditions the fin S is inconvenient when in the flat position, as represented in Fig. 5. In order to maintain the fin 8 in a conven-' icnt position to be seized when the cup is withdrawn from the dispensing cabinet, and to serve as a handle when drinking'from the cup, I fold the fin 8 back against the side flap 2 of which it forms a part, but without breaking or crushing the fibers of th material on the line 14 of fold, thereby a1 owing the elasticity of the material on its line 14 of fold to restore the fin to and maintain it normally in a raised position substantially at right angles to the drinking cup, as represented at 15, in Fig. 7.

In Figs. 8 to 11, inclusive, I have shown a' the cup, whereas, in the construction shown in Figs. 8 to 11, the attached edge of the fin is at one side of the center line of the cup.

' Referring to Fig. 8, I have shown an extended blank according to my modified form of construction, in which. 16 represents the body portion of the drinking cup, and 17, '18

the two side flaps which are folded gren z upon 1e y por ion 0 t Finkihg cup on the dash and dot lines 19 and 20. The under side of the side flap 18 is provided with gum, as shown at 21, Fig. 8. Tli sidc flap 18 is first folded upon the body of the drinking cup, and the side flap 17 is folded over to overlap the gunnned edge of the side flap 18, as shown in Fig. 9. the attached surfacesoijheinlosiilnfiapsbeing included between the broken lines and 23, FigT ff. The side flap 17 is provided with a projecting fin 24 which, when the cup is folded, as shown in Fig. 9, lies fiat against the side flap 18. The fin is then folded back upon itself upon the broken line 2:), Fig. 9, as represented at 26, Fig. 10.

By avoiding the crushing or breaking of the fibers at the folded edge 27 the elasticity of the material will raise the folded ed 'e 26, causing it to stand'at an angle to tile side of the cup, as represented at 28, Fig. 11. This method of folding the fin allows the fin to be raised either by the free edge 30 orby the folded edge 27, facilitating. the withdrawal of the cup from a dispensing cabinet 1 of the type now in use.

I claim,

As an article of manufacture, a drinking cup formed of'fiexible sheet materiah haring a body portion and two side flaps folded over said body portion and united at the overlapping edges, with one of said side flaps provided with an extension projecting over the other side flap, with a portion; of said extension folded upon itself tofform-a doubled edge and allow the extension to be raised by either its free edge or byit's folded edge. v i .1
